Benefits of technology

The present invention allows a UE (user equipment) to better understand the configuration information of neighboring cells, which leads to more accurate measurements. This is achieved by redefining messages in the existing method without adding extra signaling overhead. As a result, more subframes can be measured to improve measurement accuracy.

Problems solved by technology

In the broadcast information, however, some problem exists in message definition, which tends to make the UE unable to accurately learn about MBSFN configurations of the neighboring cells, and thus unable to accurately obtain a strategy for measuring the signals from the neighboring cells.

Embodiment Construction

[0017]In the following, detailed descriptions of well-known functions or equipments are omitted, to avoid any redundancy.

[0018]Now, the present invention is described with reference to FIG. 2.

[0019]At Step 201, a BS of the serving cell transmits the MBSFN subframe configuration information of the serving cell to a UE in the serving cell via a broadcast control channel (BCCH).

[0020]At Step 202, the BS of the serving cell transmits to the UE information on a subset relationship of the MBSFN subframe configurations of neighboring cells relative to the MBSFN subframe configuration of the serving cell to the UE in the serving cell.

[0021]The above information on the subset relationship of the MBSFN subframe configurations of the neighboring cells relative to the MBSFN subframe configuration of the serving cell can be transmitted to the UE with Radio Resource Control signaling (RRC signaling) or via the broadcast control channel (BCCH).

[0022]According to one implementation of the present e...

Abstract

A method and an apparatus for transmitting multimedia broadcast single-frequency network (MBSFN) subframe configuration information of neighboring cells in a wireless system is provided. The method comprises: transmitting, by a base station of a serving cell, MBSFN subframe configuration information of the serving cell to a UE which accepts services from the serving cell via a broadcast control channel (BCCH); transmitting information on a subset relationship of MBSFN subframe configurations of the neighboring cells relative to the MBSFN subframe configuration of the serving cell to the UE which accepts services from the serving cell via the broadcast control channel (BCCH); performing, by the UE, measurements on the neighboring cells according to the subframe configuration information of the serving cell and the information on the subset relationship of the MBSFN subframe configurations of the neighboring cells relative to the MBSFN subframe configuration of the serving cell.
